Fast Radio Bursts and White Hole Signals

TL;DR

This paper explores the hypothesis that Fast Radio Bursts may originate from primordial black hole explosions via white hole transitions, estimating their size and energy, and suggesting a potential link between observed signals and black hole physics.

Contribution

It introduces a simple model connecting primordial black hole explosions to Fast Radio Bursts, proposing a novel astrophysical origin for these signals.

Findings

Estimated size of exploding primordial black holes

Calculated power output of the explosion

Suggested a possible connection between FRBs and black hole phenomena

Abstract

We estimate the size of a primordial black hole exploding today via a white hole transition, and the power in the resulting explosion, using a simple model. We point out that Fast Radio Bursts, strong signals with millisecond duration, probably extragalactic and having unknown source, have wavelength not far from the expected size of the exploding hole. We also discuss the possible higher energy components of the signal.
